If you're writing with your right hand, do you know what your left hand is doing? Are you consciously controlling it? No, you are writing.
But you KNOW your left hand is there, right? You know it's not off killing people. The left and right are working together even IF you are not consciously operating both at once.
Feedback, as it were. Response, reaction, born of habit, connected and independent at the same time. Working together with individual purposes.
